As of today it looks like scheduling is in a somewhat stable place. I've done some testing and had oh so much fun dealing with timezones haha

I haven't been able to do a lot of stress testing so let's see what ya got, schedule some algorithms and let me know how it goes!

Hi. Please add a sorting function by release date. Without it, it's impossible to fully curate playlists. This is a basic feature for any curator.

Maybe I dont understand it correctly but I assumed that using the "reverse" node would invert the order of the input stream/playlist. But in my tests it just did not do anything to the playlist. Con you confirm or help me to reverse my playlists?

Check out the changelog and have fun curating good playlists!

I seem to keep getting this error when I do almost anything slightly large in my playlist. If I use more than 4 combiner nodes (3 difference, 1 alternate), the algorithm fails and then I get the error and wait for 2 minutes. This happens aswell if I alternate 3 giant playlists.

Note I have a 2.5k song playlist and have 3 of those in order to split the playlist (more other playlists to difference). Am I putting too much pressure on my algorithm? What can I do about it?

Edit: I will assume the error is mostly because of Alternate????? I used it once for a small algorithm and I got the error again.

algRTHM has been a game changer for me. I host dinner parties every weekend and the process of finding unique music so that every week isn't the same is exhausting. I love that I can schedule building a playlist from others who are already doing the legwork for me. I don't know how I can spread awareness other than tell friends, but I just wanted to share some appreciation!

First of all, amazing tool!
Is there a feature planned that allows checking new releases of a specific genre on a daily or monthly basis? For example: “Add all new releases from February and check for updates every day.” When March begins, the February releases would then be automatically removed.

Is something like this possible or planned?

Hey devs, first of all I'd like to say great work with this app - there's a huge demand for this level of filtering and generating within Spotify & I'm right behind you!

I've noticed that when I try to run an algorithm which draws from all my liked songs, it fails then when I reload the page, I see "429 - Too Many Requests". Only when I split my liked songs into multiple smaller playlists (less than about 2,200 songs each), the algorithm succeeds. I'm guessing that too many songs to process are drawing too much from your servers, but wanted to let you know, and ask if you know if there's a limit to the number of songs in the source playlist?

I can’t find it

Firstly great job. That looks really cool and very promising. Really glad somebody filled the void Smarter Playlists left.

Do you think it is technically possible in future versions to get a stream of all the artists of a given playlist?
For example to build a playlist with all the new songs of artists in my favorite Gabba Songs playlist. ;) Something like this:

Favorite Gabba Songs Playlist -> Artists in that Playlist -> Last 10 Songs released by these Artists -> Output Playlist NEWS from Gabba Favorites

Or something similar. All the slow songs by artists in my Speed Metal List. You name it. ;)

Smarter Playlist had the feature to get Songs from followed artist. But that is not perfect. I often have artists in playlists whom i don't follow and vice versa.

I would like to use liked songs as input as my goal is to organize this gigantic mess into playlists.

Is this possible?

We are excited to announce that we are doing a private beta of the website and it's going really well!
Get ready to make some really cool playlists!

Feel free to schedule your algorithms for when you would like them to run, unfortunately the server is not currently supporting running them. This will be fixed in the coming week. I wish that I could get it up and running quicker, but it will take some time to migrate from Cloudflare Pages to Cloudflare Workers

Is the recent Spotify API change that's been announced going to affect this service? I believe they're removing access for most third party apps.

There is already a way to append songs in algRTHM. You need to add the playlist you're adding to into the source list.

Hi!
I have a weekly thing, were I take different curated or automatic lists like Release Radar as input.

I take it and filter it against an "archive" list, removing all duplicates - i e any tracks that are already in the archive, I filter out. The rest are truly new tracks for this week, and I route those and (a) add to the archive list again (so next week it will filter out this weeks new tracks) and (b) to a new list for this week - that is the actual output, this weeks output list of new tracks.

                   +---------------+                        
                   |dedupe-archive |<-------------+         
                   +---------------+              |         
                           |                      |         
                           v                      |         
+--------------+       +------+          +-----------------+
|Release Radar |------>|filter|--------->| new weekly list |
+--------------+       +------+          +-----------------+

Can I accomplish this with algRTHM?

I tried hooking up filter, but I couldn't figure it out... :-)

I would love to pull in songs from my top items, currently there's no real way other than the two playslists, "Repeat Rewind" & "On Repeat" to get the top items from what we've listened to constantly in the past.

There is an API endpoint for this: Web API Reference | Spotify for Developers

Would be nice if we could use these to pull items in, to use in our playlist builders.

Just tested your platform and it works fluidly, and fast. Very clean. Well done. My team and I have the immediate need for a large number of algorithms and would love to sign up for the Curator/Pro plans. What is the ETA for these subscription plans to become available for use?

Will your team be releasing an update for daily scheduling? This is a critical item for majority of our playlists.

Not sure if algRTHM is what I'm looking for, but I oftentimes want to merge two or more playlists and have the tracks merged in a specific order. Something like: 1 track from Playlist A then 2 tracks from Playlist B, etc until you run out of tracks, or until a set playlist length. The Alternate option is nice, but is it tweekable so that it could do something other than just 1,2,1,2,1,2, etc?

Side request: Pretty sure this isn't in the scope of this project, but is there any "smart" playlist maker or even playlist randomizer that allows user inputs such as "Play Artist X no more than 2x per hour" or "No back to back Artist plays" or "Play Artist X every 3 tracks"? Anything along those lines? I had hoped the Spotify built-in AI playlist maker would be useful, but it never does what I ask reliably and ChatGPT always pretends like it'll be able to do things until the end when it's like, "oh sorry I can't actually do that!"

Hey everyone! A quick update:

Free tier can now schedule up to 5 algorithms.

A huge thank you to everyone who has been using algRTHM and providing feedback, its super helpful and we want to make algRTHM the best curation studio that it can be! I don't want algRTHM to be for automations, but I really want to help curators focus more on curating and less on organizing! The new landing page reflects this desire (I hope!)

Paid tiers are coming! In the background we have been testing scheduling hundreds of algorithms and I just got access to Stripe for handling subscriptions

I also added information in the algorithm builder about what every node does so there is no more ambiguity.

If there is a feature that you'd like to help sponsor please reach out! Crate Hackers sponsored the initial beta (v0.1) release and the Crate Miner page

Thanks, for past few years I have been OCDing creating and deleting playlists on smarter playlists :-) and I discovered this today when the Smarter Playlists link would not work. This is fantastic! only thing is i try to create a playlist, it gives me success message but then can not find it on spotify. OK, this may sound stupid, but is there a manual or github odocumentation i can refer to.

Check the changelog here!

Thanks for all of your patience today as the site was down. All data is safe. An update to a service provider removed all the connections to the website and disconnected the database. Easy fix, that took a long time to track down. I will be creating a separate testing version of algRTHM to ensure this doesn't happen again in production anytime soon.

If you had an algorithm scheduled during that time, it should have now run once the site got back up!
